Structurally, the ovary displays:
- A. on the outside, an elastic tissue;
- B. on the surface, the glandular parenchyma;
- C. the cortical area, which contains ovarian follicles;
- D. the medullar area, which contains blood vessels;
Correct Answer: C
Rationale: Step 1: The ovary is a complex organ with distinct internal structures.
Step 2: The ovarian cortex houses ovarian follicles, which are crucial for reproductive functions.
Step 3: Ovarian follicles contain oocytes and support cells for oocyte development.
Step 4: Therefore, choice C is correct as it accurately describes the structural aspect of the ovary.
Summary: Choices A, B, and D are incorrect as they do not accurately describe the structural components of the ovary. Choice A talks about elastic tissue, choice B mentions glandular parenchyma, and choice D refers to blood vessels, none of which are specific to the structural arrangement of the ovary.

The external male reproductive organs consist of the penis, testes, and
- A. urethra
- B. prostate
- C. scrotum
- D. seminal vesicle
Correct Answer: C
Rationale: The correct answer is C: scrotum. The scrotum is a pouch of skin that houses the testes, which are responsible for producing sperm and testosterone. It is considered an external male reproductive organ because it plays a crucial role in maintaining the optimal temperature for sperm production. The penis is also an external male reproductive organ, but it is not part of the scrotum. The urethra is a passage for both urine and semen, and while it is part of the male reproductive system, it is not considered an external reproductive organ. The prostate and seminal vesicle are internal male reproductive organs involved in producing and secreting seminal fluid, making them incorrect choices in this context.
The failure of a testes to descend is referred to as _____.
- A. inguinal hernia
- B. strangulated hernia
- C. vaginal process
- D. cryptorchidism
Correct Answer: D
Rationale: The correct answer is D: cryptorchidism. This is because cryptorchidism specifically refers to the failure of one or both testes to descend into the scrotum. It is a common condition in newborns and can lead to complications if not treated.
A: Inguinal hernia is the protrusion of abdominal contents through the inguinal canal, not related to testes descent.
B: Strangulated hernia occurs when the blood supply to the herniated tissue is cut off, not related to testes descent.
C: Vaginal process is a structure involved in testicular descent but does not describe the failure of testes descent itself.
Summary:
Cryptorchidism is the correct term for undescended testes, while the other options are unrelated conditions.
What is the final stage of labour?
- A. Dilation of the cervix.
- B. Delivery of the infant.
- C. Contraction of the uterus.
- D. Delivery of the placenta
Correct Answer: D
Rationale: The final stage of labor is the delivery of the placenta. This occurs after the baby is born. The placenta is essential for providing nutrients and oxygen to the baby during pregnancy, but once the baby is born, it needs to be expelled from the mother's body. This process is crucial to prevent postpartum complications.
A: Dilation of the cervix occurs in the first stage of labor.
B: Delivery of the infant happens in the second stage of labor.
C: Contraction of the uterus is a continuous process throughout labor but does not signify the final stage.
In summary, the correct answer is D because it represents the final step in the labor process, while the other options pertain to earlier stages of labor.
The initiation of puberty and menses in a female, involves increased levels of _____.
- A. FSH
- B. LH
- C. estrogen
- D. progesterone
Correct Answer: C
Rationale: The correct answer is C: estrogen. During puberty in females, the hypothalamus signals the pituitary gland to release hormones, leading to increased estrogen levels. Estrogen plays a key role in the development of secondary sexual characteristics and the onset of menstruation. FSH and LH are also involved in the menstrual cycle but do not directly initiate puberty. Progesterone is mainly involved in the menstrual cycle's later stages, not the initiation of puberty.
Absence of menstruation
- A. Rhinorrhea
- B. Amenorrhea
- C. Menorrhagia
- D. Leucorrhea
Correct Answer: B
Rationale: The correct answer is B: Amenorrhea. Amenorrhea refers to the absence of menstruation, which can be caused by various factors such as hormonal imbalances, stress, pregnancy, or medical conditions. Rhinorrhea (A) is the medical term for a runny nose, unrelated to menstruation. Menorrhagia (C) is excessive menstrual bleeding, the opposite of absence of menstruation. Leucorrhea (D) is a vaginal discharge, not related to the absence of menstruation. Therefore, B is the correct answer as it directly addresses the absence of menstruation.
